SELF-CLOSING COCK.

sPEcIFIcA'rion' forming part of Letters Patent No. 627,671, dated June 27, 1899. Application filed February 10, 1899. Serial No. 705,167. (No model.)

To all whom it may concern.-

Be it known that I, JOHN KELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Self-Closing Cocks, of which the following is a specification.

The object of my improvement is to simplify the construction of a self-closing cock by omitting any variety of connection with the operating-stem requiring it to be rotated to open the valve and substituting therefor a connection between the operating-stem and valve,whereby the stem need be merely turned on a fulcrum at an angle to its longitudinal axis to efiect opening of the valve.

The accompanying drawing illustrates my improvement applied to a self-closin g cock of a valve F.

one end to the valve, extends longitudinally the faucet Variety, shown in longitudinal section with a diagrammatic dotted-line representation of the manner of operation.

A is the shell, shown in the conventional form employed'in a faucet, having screwed upon it the tubular extension B and containing the valve-chamber and a valve-seat G for The valve-stem E, fastened at in the chamber and is provided at its opposite end with an eye E, preferably of V shape in cross-section about its inner circumference, as indicated.

D is the operating-stem, extending through a stuffing-box C, provided between the ends of the shell A and preferably containing a spring H, shown in its preferred form of a sleeve of soft rubber closely fitting the box C and closely surrounding the portion of the operating-stem contained therein, which is shown as bearing against the outer end of the rubber sleeve through the medium of a flange a, affording a fulcrum, rounded about its upper surface to conform to and fit the upper end of the box 0. D enters the eye E in the valve-stem, and the drawing shows an operating-handle D, connected with the outer projecting end of the operating-stem, though neither the handle nor the rubber packing His an indispensable feature of my invention.

Any suitable form of spring may be substituted for the rubber sleeve; but a spring, though desirable,may without departure from The lower end of the stem my invention be entirely omitted and the. fluid-pressure behind the valve depended on for its closure.

To open the valve F, the operator by exerting pressure against the outer projecting port-ion of the stem D, using the flange a as a fulcrum, forces the operating-stem to the position indicated by dotted lines, whereby the resultant displacement of its lower end engages it with the eye E to press the inner end of the valve-stem backward and unseat the valve. A handle D facilitates the operation and requires therefor merely to be pressed downward to the dotted-line position represented.

What I claim as new, anddesire to secure by Letters Patent, is

1. In a self-closing cook, the combination with a shell containinga chamber anda valveseat therein, of a stuffing-box extending laterally from said shell, a valve having a stem in said chamber, and an operating-stem extending lengthwise through said stuffing-box into said chamber and into engagement at its inner end with said valve-stem and provided between its ends with a flange on which it is fulcrumed in said stuffing-box to adapt it to be turned on its fulcrum to actuate said stem lengthwise to unseat the valve, substantially as described.

2. A self-closing cock comprising, in combination, a shell containing a chamber and a valve-seat therein, a stufling-box extending laterally from said shell and containing a spring, a valve having a stem in said chamber, and an operating-stem, extending lengthwise through said stuffing-box into said chamber and into engagement at its inner end with said valve-stem and fulcrumed between its ends to be turned on its fulcrum in a plane lengthwise of said stem to actuate it to unseat the valve, substantially as described.

3. A self-closing cock comprising, in combination, a shell containing a chamber and a valve-seat therein, a valve F having a stem E, a stuffing-box C containing a rubber sleeve H, and an operatin g-ste m D extending through said stuffing-box into said chamber to engage therein with said valve-stem and provided with a flange or atwhich it seats and fulcrums on. said sleeve, whereby turning the operatin g-stem on its fulcrum moves the valve-stem to unseat the valve, substantially as described.

4. A self-closing cock comprising, in 00111- bination, a shell containing a chamber and a valve-seat therein, a valve F having a stem E provided with an eye E, a stufling-box C containing a rubber sleeve II, and an operating-stem D extending through said stuflingbox into the chamber to engage said eye and provided with a flange a at which it seats and fulcrums on said sleeve, whereby turning the operating stem on its fulcrum moves the valve-stem to unseat the valve, substantially as described.
